Could you please let us know Min and Max value of AISENSE at TA=-40 ℃ to 85 ℃ ?
Because, we would like to know the error of ITRIP without error of xVREF and RISENSE.
Part Number: DRV8834 Hi, I'm using DRV8834 to drive a small stepper motor to open/close an air vent. If a user manually opens the vent, we think the backdrive may be causing a small number of field failures as the energy from the manually rotated motor…
Part Number: DRV8834 Hi team,
Here's an issue from the customer may need your help:
When using the DRV8834 to control the stepper motor, the indexer mode of 8834 is required (16 microsteps are used simultaneously). In addition, the peak of the output…
Part Number: DRV8834 Other Parts Discussed in Thread: DRV8843 , , TCA6416A Hi team,
Can you have a look at the following customer inquiry, please?
In a test setup we are currently using the DRV8843 to control a stepper motor.
I noticed contradictory information…
Part Number: DRV8834 Hi Team, May I ask for help? Our customer have a concern as shown below: "Are there any TI stepper motor drivers that has 1-phase excitation mode when running in full-step mode? All I have found are only supporting 2-phase excitation…
Part Number: DRV8834 Hi All,
Our smart glasses project needs to use a stepping motor to achieve diopter adjustment and interpupillary distance adjustment functions. The specific parameter requirements are as follows:
1) D iopter adjustment: 3.6V input,…
Part Number: DRV8834 Other Parts Discussed in Thread: DRV8434 Hi team,
Stepper motor specifications: 2-phase, 1.8 degrees, 4.9 V nominal, 0.7 A nominal, 7 ohm phase resistance, Phase inductance of 5 mh.

Part Number: DRV8834 Other Parts Discussed in Thread: DAC60502 , Hi team,
Is it possible to dynamically adjust the current maximum of the 8834 by connecting the two analogue outputs of the DAC60502 chip directly to the AVREF and BVREF pins of the DRV8834…
Part Number: DRV8834 Hello,
I am using a 5v bipolar stepper motor with the drv8834.
config is in indexer mode (permanently tied, not GPIO controlled)
m pins selected for full steps (permanently tied, not GPIO controlled)
Sleep pin connected to logic high…
